ments such as organs and pianos, two of several illustrations.

One of the primary objects of the invention is the provision of an article of the character set forth which is simple in construction, susceptible of inexpensive and easy inaniuiacture' and by which accurate tracking is insured.

In the drawings accompanying and forming part of the present specification I have shown in detail two of the several convenient forms of embodiment of the invention which to enable those skilled in the art to practise the same will beset forth fully in the following description. I do not restrict myself to this disclosure; I may depart thcre'l'romj in several respects within the scope of the invention defined by the claims following said description.

Referring to said drawings: Figure 1 is a. view of a music sheet conipi .sing my inven-. tion, the intermediate portion of the sheet being removed and the ends brought together. Fig. 2 is a detail view of a portion of said sheet. Fig. 3 is a cross section of the sheet, showing a contact-linger in elevation. Fig. l is a view corresponding to Fig. 3, of a inodilicd form of sheet.

Like characters refer to like parts throughout the several vicws, thc last three of which arc on larger scales than. Fig. 1.

As will be inferred from what has been noted I do not limit myself to the use oi the sheet in connection with any particular t vpo of apparatus: the latter may be an organ. piano or other instrument: in fact there may be instanccs where the device to .bc nltimatcly opcrntcd is not musical, the title adopted being merely a convenient one.

Patent-ed June 20, 1916,

I might add that this application is a division of my conteinporaneously-pending application, filed September 19, 1913, Serial No. 790,675.

In Figs. 1 to 3 the music-sheet is denoted by 2, and it may agree in outline with those now in general use, this being an immaterial detail. It may be of any suitable material, for example paper or other suitable insulating material. The substance of which the sheet 2 is made, however, is not a matter of moment, the invention not concerning this point. Said. sheet has longitudinally-extending positive guides of suit I able kind. In Figs. 1, 2 and 3 said positive guides 3 are in the form of parallel grooves or channels. In the sheet 4 in Fig. 4; the longitudinally-disposed positive guides consist of parallel ribs, beads or tongues 5. Coope 'ative with the sheet 2 are suitable mem ber one of which is shown in Fig. 3 and as consisting of a contact-finger 6 of elec trical conducting material. This finger (3 like its mates (not shown) is resilient, and

its free end is adapted to be entered into one of the channels 3 so as to be/ accurately directed by said channel toward and into a note perforation or slot as Y of which there are several of diiterent lengths intersecting said channel. In Fig. 1 the arrow-directs the line of movement of the music sheet 2. It will be assumed that one of these resilient fingers (5 is in the entering end of a cooperating channel or groove 3 and the longitudinally corrugated sheet is moving in the direction indicated. The result will be that when an opening 7 comes opposite the free end of the finger, said end by tpe resilienceof the finger will be sprung tirough said note perforation or slot and against a. cooperating contact over which the sheet travels and thereby in a manner familiar in the art, close a circuit to efi'ect the action of an organ key or sounding of an organ pipe or the performance of some equivalent act. The contact finger S of Fig. 4: is bifurcated at ll at its free end to straddle the ribs or tongues 5, there being in both cases as will be inferred tongue and groove guide connection between the music sheet and a fin'ger or fingers. In connection with each of the guide portions 3 and preferably located at the front or leading end'thereof is a posi ion tioningZhpcningas'11 which as shown conment of the sheet the free ends of the fin-- gers will be correctly guided into the entering ends of the grooves In Fig. 4 the tongues or ribs 5 are interis to permit the projection of the free end of the contact finger 8 against a cooperating inemher when a slot '10 is brought opposite the free end of a finger 8 on the movement of the sheet 4.

In both forms of the invention the sheet is corrugated, the cmrugations extending longitudinally. In one form of the device the grooves of the corrugated portion of the sheet constitute contact guides, while in the other form the beads of the corrugated portion act as such contact guides.

What I claim is:

1. A music sheet 'of insulating material having note perforations and also having contact guides intersected by the perforations. 4

Q. A music sheet of insulating material having several series of note perforations, the perforations of the respective series being in alinement longitudinally of the sheet, said sheet also having contact guides extending in parallelismwith each other longitudinally-of the sheet, each guide be ing intersected by the perforations of a series.

3. A music sheet of insulating material having longii ulinaLly extending grooves and also having note perforations intersecting the respective grooves.-

4. A music sheet of paper having a series of longitudinally extending grooves disposed in'parallelism with each other and also having series of note perforations intersecting the respcctive'grooves.

A music sheet of insulating material ha ving contact guides and also having note perforations intersecting the respective guides. each guide having a contact posi- 'tioning portion connected with it.

(3. A music sheet of insulating material having a plurality of longitiulinally extending guide grooves, a plurality of note periiorations in longitiulinally extending contact rows, the l'ieri'orations oi the rows in tersecting the respective guide grooves. and contact positioning openings in (:01llIIllliliC;ltion with the leading ends of said grooves.

T- A music sheet of paper having a plu ral n of longitudinally extending parallel grooves and also having rows of note persected by the slots 10, the purpose of which 4' sheet,- the forations, each groove being intersected by the perforations of a row.

8. A music sheet of insulating material having'a longitudinally extending contact guide groove and also having a note perforation intersecting the groove.

9. A music sheet of insulating material having a'longitudinally extending contact guide groove and also having a note per foration intersecting the groove, said sheet having a contact positioning opening in connnunication with. and wider than the groove. I I

10. A music sheet of insulating material having note perforations arranged in series, said sheet being also corrugated, the corru gated portions of the sheet presenting contact guides cooperative with the respective series of perforations.

11. A music sheet of insulating material having note perforations arranged in series and. also having contact guide grooves co operative with the respective series of perforations.

12. A music sheet of insulating material having note perforations and also having means constituting a part of the sheet and located between the sides thereof for positively guiding contacts into and out of the respective perforations.

- 13. A music sheet of insulating matezial having longitudinally disposed rows of perforations and also having longitudinally disposed contact guide grooves coiiperativc with the respective rows of perforations.

14. A music sheet of insulating material adapted to longitudinally travel and having av longitudinally disposed series of note perforations and also having a contact guide portion approximately coextensive with the said perforations between the sides of the contact guide portion being adapted to positively guide a contact into and away from the perforations on the travel of the sheet.

A music sheet of insulating material having a longitudinally extending contact guide groove. and also having a series of note perforations approximately coextensive with the groove longitudinally of the sheet, said sheet also having a contact positioning opening independent of the perforations in couununication with and wider than the groove.

In testimony whereof l allix my signature in presence of two witnesses.
